Purpose : Authors experienced cases of chronic ACL tear with spur-like lesion on the tibial condyle which is different from the lateral capsular sign and degenerative change and evaluated the significance of 'spur-like lesion' in relations with chronic ACL injury. Material and Method : We have 5 patients with spur-like lesion on the lateral tibial condyle in simple radiogram. The location, shape and size of the lesion were studied using radiogram and MRI. Cause of injury, associated injury and chronicity of the ACL tear were analyzed. All 5 patients were male, and mean age was 33.8 $(17\~46)$ years. Result : The spur-like lesion was located from 3.8 mm(avg.) below the articular surface of the lateral tibial condyle to the apex of the fibular head and protruded laterally or inferolaterally from just posterior to the Gerdy's tubercle with a round or sharp-end triangular shape. Average length was 6 mm and average width ortho base was 9.2 mm. The cause of injury were sports jnjury 4 cases and traffic accident in one. The chronicity of the ACL tear was average 10.7(8 months$\~$23 years) years and medial meniscus tear was shown in all cases and lateral meniscus tear in three. Conclusion : We suggest that a patient who has a history of trauma with spur-like lesion on the lateral tibial condyle of the knee is expected to have chronic ACL tear.
Objective: We have studied the effects of acupuncture and low level He-Ne laser therapy(LLLT) at $SI_3$, $BL_{40}$ on the tibial, sural nerve injury due to sports-damage or traffic accident and L5 spinal nerve ligature model like general herniation of nucleus pulposus(HNP) in a rat of neuopathic pain. Methods: A model of neuropathic pain was made by injuring tibial nerve and sural nerve while common peroneal nerve was maintained. Also, it was made by isolating left 5th lumbar spinal nerve. Three weeks after the neuropathic surgery, acupuncture and LLLT was injected at $SI_3$,$BL_{40}$ one time a day for one week. LLLT was divided three groups, that is LLLT-1(5mW), LLLT-2(10mW) and LLLT-3(30mW). After that, we examined the withdrawal response of neuropathic rats' legs by Von frey filament and acetone stimulation. And also we examined c-Fos, Nocieptin and KOR-3 in the midbrain central gray of neuropathic rats. Results: As we have observed the effect of mechanical allodynia, LLLT-3 group were diminished on 4 day, 5 day, 6 day and 7 day in the resection model compared with control model, LLLT-1 group were diminished on 5 day, LLLT-2 group were diminished on 3 day and 6 day, LLLT-3 group were diminished on 3 day, 4 day, 5 day, 6 day and 7 day in connected model compared with control group. As we have observed the effect of cold allodynia, LLLT-3 group were diminished on 7 day in the resection model compared with control model, LLLT-1 group were diminished on 6 day, 7 day, LLLT-3 group were diminished on 7 day in connected model compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, LLLT-3 were diminished in resection model compared with control group, LLLT-1 group were diminished in connected model compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, resection model were not increased compared with control group, LLLT-1 group and LLLT-3 group were increased in connected model compared with control model. As we have observed the effect of activity of KOR-3 in the central gray part, resection model were not increased compared with control group, LLLT-3 group were increased in connected model compared with control model. Conclusions: We have noticed that LLLT-1 and LLLT-3 group have more controllable effect than acupuncture group. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin and KOR-3 have effectively to control pain. Therefore We have to follow up about that.
In this study, the lower limbs joints were analyzed for features based on the biomechanical characteristics of landing techniques according to height and landing on the ground type (flats and downhill). In order to achieve the objectives of the study, changes were analyzed in detail contents such as the height and form of the first landing on the ground at different angles of joints, torso and legs, torso and legs of the difference in the range of angular motion of the joint, the maximum angular difference between joints, the lower limbs joints difference between the maximum moment and the difference between COM changes. The subjects in this study do not last six months did not experience joint injuries 10 males in 20 aged were tested. Experimental tools to analyze were the recording and video equipment. Samsung's SCH-650A model camera was used six units, and the 2 GRF-based AMTI were used BP400800 model. 6-unit-camera synchronized with LED (photo cell) and Line Lock system were used. the output from the camera and the ground reaction force based on the data to synchronize A/D Syc. box was used. To calculate the coordinates of three-dimensional space, $1m{\times}3m{\times}2m$ (X, Y, Z axis) to the size of the control points attached to the framework of 36 markers were used, and 29 where the body was taken by attaching a marker to the surface. Two kinds of land condition, 40cm and 60cm in height, and ground conditions in the form of two kinds of flat and downhill slopes ($10^{\circ}$) of the landing operation was performed and each subject's 3 mean two-way RM ANOVA in SPSS 18.0 was used and this time, all the significant level was set at a=.05. Consequently, analyzing the landing technique as land form and land on the ground, the changes of external environmental factors, and the lower limbs joints' function in the evaluation were significantly different from the slopes. Landing of the slop plane were more load on the joints than landing of plane. Especially, knee extensor moment compared to the two kinds of landing, slopes plane were approximately two times higher than flat plane, and it was statistical significance. Most of all not so much range of motion and angular velocity of the shock to reduce stress was important. In the further research, front landing as well as various direction of motion of kinetic, kinetic factors and EMG variables on lower limbs joints of the study in terms of injury-prevention-approach is going to be needed.
The purpose of this study was to verify whether there are any differences in the level of exercise self-efficacy and perceived health status according to the stage of change for exercise behaviors in older adults. The subjects consisted of 231 older adults (91 male, 140 female) by convenience sampling residing in city D. The collected dates were analyzed using one-way ANOVA, Tukey HSD, and simple regression analysis by SPSS WIN 21.0 program. Moreover, all statistical significance level was set at a=.05. The study results were as follows: Analysis of variance showed that exercise self-efficacy showed significant differences according to the stage of change for exercise behaviors, and as a result of the posthoc analysis, it was found that as the stage became higher, their exercise self-efficacy became higher as well. Perceived health status showed significant differences according to the stage of change for exercise behaviors, and as a result of the posthoc analysis, it was found that as the stage became higher, their perceived health status became higher as well. Analysis of variance showed that exercise self-efficacy and perceived health status were significantly associated with the stages of exercise behavior change. This study identified that exercise self-efficacy and perceived health status were significant variables to explain a possible relationship with exercise stages of older adults. This study provides new information to influence the development of the better health promotion and exercise intervention for older adults in the community.
The purpose of this study was to investigate the relationship between psychomotorik and brain function in domestic and foreign literature, and to clarify the mechanism of psychomotorik from the viewpoint of brain science, and to provide the teachers, therapists, The purpose of this study is to provide basic data which can enhance the understanding of the mechanism of psychomotorik. From the viewpoint of brain science, the study of domestic and foreign literature related to the mechanism of psychomotorik and the positive learning environment and various physical experiences in early life through the movement of psychomotorik are very important from the brain physiological point of view. The results of this study showed that the more the children move, the more the learning is improved and the healthy emotional control ability is improved and the brain is more likely to be optimized. Therefore, it is considered that this study, which has been studied through the brain science approach, provided very important basic information to understand the relation between movement of psychomotorik and brain function. In particular, understanding the possibility of optimizing the brain by cultivating a healthy emotional control ability and improving learning as children move more and more is considered to be a necessary process for educating our children well in the future. Until now, research on psychomotorik and brain function was lacking. Through this study, I hope that more people will have an opportunity to expand their understanding of the psychomotorik.

The purpose of this study was to examine the influence of the exercise performance of yoga and pilates on the autonomic nervous system in an effort to provide some clinical information on exercise prescription. The subjects were 20 selected college students who majored in P.E. A yoga group and a pilates group were organized with 10 students respectively, the autonomic nervous system of the students was measured before the exercise, immediately after that and 30 minutes after recovery. The findings of the study were as follows: First, there were significant differences in the yoga group's stress index and average pulse according to the main effect of the time and interaction effect between the time and group. Second, there were significant differences in the yoga group's sympathetic nervous system activity and autonomic nerve balance according to all the main effect of the time, interaction effect between the time and group and the main effect of group. Third, there were significant differences in HRV(Heart Rate Variability), parasympathetic nervous system activity, SDNN, and RMSSD according to the main effect of the time, and interaction effect between the time and group and the main effect of group produced no statistically significant differences. In conclusion, yoga seemed to be effective at lowering stress index and average pulse. Specifically, yoga exercise seemed to exert a more positive influence on the decrease of sympathetic nervous system activity and autonomic nerve balance than pilates exercise.
The purpose of this study was to examine the effect of the education intervention program as a nutrition program and exercise for the improvement of metabolic syndrome in women who voluntarily participated in health program in public health centers over 30 years of age. The subjects of this study were 120 women who completed the 12 - week obesity clinic program among the 400 obesity clinic participants in the northeastern of Seoul. Exercise and nutrition programs were administered on a daily basis for 1 hour every week for 12 hours with exercise and nutrition for 1 week to assess the effect of the participants on the risk factors of metabolic syndrome in health program. The metabolic syndrome and the risk of the disease were examined by analyzing the metabolic syndrome risk factors, change magnitude and change rates before and after the intervention. Waist circumference(p <.001), systolic blood pressure (p <.001), diastolic blood pressure (p <.001) and body mass index (p <.001) decreased during the 12 - week health program. Body weight (p <.01), waist circumference (p <.05), BMI (p <.01) and fat mass (p <.05) decreased more in the age group below 50 years.

The purpose of this study is to determine the evaluation of affected visual landscape of Taereung National Training Center to Taereung and Gangneung UNESCO World heritages, South Korea. For this research, it used to offer the affected visual landscape rate and 3D simulation with Sketch up 8.0. This study conducted over 4 steps. Step 1, view points are selected with literature review and interview. Step 2, with Sketch up created 3D modelling and calculated the affected rate on the landscape. Step 3 individual buildings were mapped with the affected rate. Lastly, step 4 were identified the results through field research. From this results, the visual landscape of Taereung and Gangneung that are damaged by the Taereung National Training Center did not appear higher than initially expected. The entrance area on Gangneung, however, where is affected from Oryungwan, Korea Sports Institute, Philseung Gym needs to establish a way to improve that landscape impact. In case of Taereung, it did not appear damaged due to the hiding effect of the forest. By field survey to confirm those results, it shows seasonal differences. In the case of the summer and autumn derive similar results with 3D simulation but were exposed buildings in the winter and spring. It means when the simulation based on the summer and fall operates, it may not reflect the affected landscape of certain times such as winter and spring. This study has significance as a basic research to co-exist between the traditional heritage and modern heritage.
Objective : The purpose of this study was to conduct biomechanical analysis of varying backpack loads on the lower limb movements during downhill walking over $-20^{\circ}$ ramp. Method : Thirteen male university students (age: $23.5{\pm}2.1yrs$, height: $175.7{\pm}4.6cm$, weight: $651.9{\pm}55.5N$) who have no musculoskeletal disorder were recruited as the subjects. Each subject walked over $20^{\circ}$ ramp with four different backpack weights (0%, 10%, 20% and 30% of body weight) in random order at a speed of $1.0{\pm}0.1m/s$. Five digital camcorders and two force plates were used to obtain 3-d data and kinetics of the lower extremity. For each trial being analyzed, five critical instants were identified from the video recordings. Ground reaction force, loading rate, decay rate, and resultant joint moment of the ankle and the knee were determined by the inverse dynamics analysis. For each dependent variable, one-way ANOVA with repeated measures was used to determine whether there were significant differences among four different backpack weight conditions (p<.05). When a significant difference was found, post hoc analyses were performed using the contrast procedure. Results : The results of this study showed that the medio-lateral GRFs at RHC in 20% and 30% body weight were significantly greater than the corresponding value in 0% of body weight. A consistent increase in the vertical GRFs as backpack loads increased was observed. The valgus joint movement of the knee at RTO in 30% body weight was significantly greater than the corresponding values in 0% and 10% body weight. The increased valgus moment of 30% body weight observed in this phase was associated with decelerating and stabilizing effects on the knee joint. The results also showed that the extension and valgus joint moments of the knee were systematically affected by the backpack load during downhill walking. Conclusion : Since downhill walking while carrying heavy external loads in a backpack may lead to excessive knee joint moment, damage can occur to the joint structures such as joint capsule and ligaments. Therefore, excessive repetitions of downhill walking should be avoided if the lower extremity is subjected to abnormally high levels of load over an extended period of time.
The purpose of the present study was to clarify the sexual difference of the Heath-Carter somatotype related variables in boys and girls from 7 through 19 years of age. In the study design, the subjects and the methods were used by the cross-sectional investigation. The subjects participated in this study were 7 through 19 years of age who belonged to typical primary, junior, senior high school and college students, and about 250 males and 250 females in each group and both sexes. Therefore, the total subjects were 3,046 males and 2,984 females. All subjects of this study lived in Pusan metropolitan city, Korea. Somatotype was calculated by the Heath-Carter's anthropometric somatotype method, In this study, in attaiment rates of sum of 4 sites skinfold and endomorphy growth, girls were significantly higher than boys in all ages intervals except through 13 years of aged groups, respectively. In attainment rates of humerus and femur breadths growth, boys were significantly higher than girls in all ages interval except 13 through 15 years of aged groups, respectively. In attainment rate of arm circumference growth, boys were significantly higher than girls in all ages interval except 7 years of aged group. In attainment rate of calf circumference growth, boys were significantly higher than girls in all ages interal except 15years of aged group. In attainment rate of ectomorphy growth, boys were significantly higher than girls in all aged interal except 8 thorough 12 years of aged groups. This results suggests the urgent necessity of developing systematic and sperate progams to treat such sexual difference in boys and girls.
